The interface connected to the amplifier provides long range communication (up to 5km) on reserved channels. The nodes work as routers/APs that provide access to "normal" WLAN devices (this is where the second wireless device comes into play). So:
* two WLAN devices: 1x long range with amplifier, 1x short range as AP
* different regulatory settings: the regulatory rules for the device with amplifier differ from those without amplifier.

This is not required. Currently both use channels in the 2.4GHz range, but there is a very good chance that we will move into the 5GHz range for the amplified backbone (yes, we know that this will come at a cost).

Thanks for taking an interest
